80 Years Later, GCHQ Releases New Images of Nazi Code-Breaking Computer (arstechnica.com) 79

An anonymous reader quotes a report from Ars Technica: On Thursday, UK's Government Communications Headquarters (GCHQ) announced the release of previously unseen images and documents related to Colossus, one of the first digital computers. The release marks the 80th anniversary of the code-breaking machines that significantly aided the Allied forces during World War II. While some in the public knew of the computers earlier (PDF), the UK did not formally acknowledge the project's existence until the 2000s.

Colossus was not one computer but a series of computers developed by British scientists between 1943 and 1945. These 2-meter-tall electronic beasts played an instrumental role in breaking the Lorenz cipher, a code used for communications between high-ranking German officials in occupied Europe. The computers were said to have allowed allies to "read Hitler's mind," according to The Sydney Morning Herald. The technology behind Colossus was highly innovative for its time. Tommy Flowers, the engineer behind its construction, used over 2,500 vacuum tubes to create logic gates, a precursor to the semiconductor-based electronic circuits found in modern computers. While 1945's ENIAC was long considered the clear front-runner in digital computing, the revelation of Colossus' earlier existence repositioned it in computing history. (However, it's important to note that ENIAC was a general-purpose computer, and Colossus was not.)

GCHQ's public sharing of archival documents includes several photos of the computer at different periods and a letter discussing Tommy Flowers' groundbreaking work that references the interception of "rather alarming German instructions." Following the war, the UK government issued orders for the destruction of most Colossus machines, and Flowers was required to turn over all related documentation. The GCHQ claims that the Colossus tech "was so effective, its functionality was still in use by us until the early 1960s." In the GCHQ press release, Director Anne Keast-Butler paid tribute to Colossus' place in the UK's lineage of technological innovation: "The creativity, ingenuity and dedication shown by Tommy Flowers and his team to keep the country safe were as crucial to GCHQ then as today."

            What's with all this killing people? How about cultivating tolerance & educating people about the benefits of tolerance & the dangers of intolerance?

            In addition, most countries already have laws that prevent the most extreme forms of intolerance & some have laws against intolerance against demographic groups, e.g. women, people of colour, LGBTQ+, people with different religions or no religion (secular state), etc..

            There's really no need to go around killing people. We just need to be a bit more pro-active about cultivating the societies that we should have, i.e. beneficial & pleasant for everyone.

The difference between Colossus and ENIAC was the latter was electronically programmable in later iterations (initially it was programmed like Colossus) whereas Colossus required you to physically change the system via plug boards to program it.

            The main leap forward that Colossus made was that it was the first large scale vacuum tube machine in the world. Until that point there was considerable doubt as to if a machine with more than 1000 vacuum tubes would be practical. As well as drawing a lot of power and producing a lot of heat, it was thought that vacuum tubes were unreliable, so having more than 1000 all working at once would be impossible.

            The cause of the unreliability was mostly the heater elements. Vacuum tubes need to be warmed up to work, so have a small electric heater in them, basically a lightbulb filament. Flowers' believed that most failures were due to thermal cycling putting stress on the heating elements, and by keeping them on all the time that could be avoided. He was able to convince others and Colossus was born.

We shouldn't forget the Z4 which also came out in 1945 and had a conditional branch instruction (though the Z3 was technically Turing competed, the Z4 meant it).

For ENIAC, it was days of rewiring and re debugging to get the same program to run again.
